Hi Serg,

> In the /etc/resolve.conf i see OLD RECORDS for DNS Server !!

please define "OLD RECORDS"...

Judging from the subject line, you've configured your machine as a dhcp client. Have you checked what the DHCP server is handing out? Did you receive a DHCP reply at all? What's in the logs, what are the time stamps of the corresponding files (especially the .info file from the DCHP client, /etc/resolv.conf) and have you probably deactivated automatic modification of /etc/resolv.conf?

structural approach:
- does your machine actually issue a DHCP request on boot?
- does your machine receive a DHCP reply?
- does the DHCP reply contain the proper values?
- does the DHCP client try to update resolv.conf?
- is resolv.conf updated at all (but probably with wrongs values)?
